How to read this directory: Providers are listed by Medicare service volume, which reflects only
Medicare fee-for-service patients (typically 65+). This does not represent total practice volume.
Industry payments span multiple years and payment types; disclosure alone establishes neither wrongdoing nor legality.
Infectious Disease includes multiple subspecialties with different practice patterns.
